CertificateSigningRequest encodedCSR clarity issue

[2f5f3a1b567e0611949455401526cba2]

The CertificateSigningRequest takes encodedCSR
which says: "Base64 encoded CSR" but unlike other calls does not mention
unlike other cases, "(PEM without headers)"
I propose either having "(PEM without headers)" or "(PEM with headers)" for clalrity
